Baker said she’s been crafting a series of essays exploring the funny side of her experiences with the disease since 2007, when she lost sight in one of her eyes. She also blogs about having MS and stays connected to others throughout the world with the disease.

MS is an unpredictable, often-disabling disease of the central nervous system that interrupts the flow of information within the brain, and between the brain and body.

“I decided early on I was going to be all in or all out with MS,” Baker said.

Her teenage daughter, Ruby Baker-Poveromo, had this to say about her mother’s MS blog: “I read it a few times and there are some embarrassing stories that make fun of me in it.”

Next weekend, Ruby and her mom will participate in the annual MS Challenge Walk on Cape Cod for the third year in a row. They raised $5,000 last year, and this year they will help from the sidelines.

The walk is a three-day, 50-mile walk to raise money for the National Multiple Sclerosis Society.

Ruby, a student at Milton High School, said she’s learned many lessons having a mom with multiple sclerosis. She said her mother is “independent and strong” and has taught her that “everybody you meet is going through some battle.”

Baker said taking part in last year’s walk “was amazing. I’m sure many mothers and teenage daughters clash. Spending three solid days together was very good. It was mostly bonding and bickering.”

Baker described herself as “very hopeful. I tell people all the time, I don’t plan to die of MS. I don’t think I’m going to die of MS. I think there will be a cure in my lifetime, particularly in this area. There’s so much MS research being done.”

When Baker was first diagnosed, Ruby was only 11. Since then, several new medicines for treating MS have become available.

Baker said she has reassured Ruby that she won’t necessarily end up in a wheelchair.

“Not everyone with MS ends up in a wheelchair,” she said.
